Cleaning And Maintenance; Problem Solving - Hoover HVI 640 Instructions For Use And Installation

CLEANING AND MAINTENANCE

• Before carrying out any maintenance work on the hob, allow it
to cool down.
• Only products, (creams and scrapers) specifically designed for
glass ceramic surfaces should be used. They are obtainable
from hardware stores.
• Avoid spillages, as anything which falls on to the hob surface
will quickly burn and will make cleaning more difficult.
• It is advisable to keep away from the hob all substances which
are liable to melt, such as plastic items, sugar, or sugar-based
products.
MAINTENANCE:
- Place a few drops of the specialised cleaning product on the
hob surface.
- Rub any stubborn stains with a soft cloth or with slightly damp
kitchen paper.
- Wipe with a soft cloth or dry kitchen paper until the surface is
clean.
If there are still some stubborn stains:
- Place a few more drops of specialised cleaning fluid on the
surface.
- Scrape with a scraper, holding it at an angle of 30° to the hob,
until the stains disappear.
- Wipe with a soft cloth or dry kitchen paper until the surface is
clean.
- Repeat the operation if necessary.
A FEW HINTS:
Frequent cleaning leaves a protective layer which is essential to
prevent scratches and wear. Make sure that the surface is clean
before using the hob again. To remove marks left by water, use
a few drops of white vinegar or lemon juice. Then wipe with
absorbent paper and a few drops of specialised cleaning fluid.
The control knobs can be removed for a complete cleaning.
The glass ceramic surface will withstand scraping from flat-
bottomed cooking vessels, however, it is always better to lift them
when moving them from one zone to another.
NB:
Do not use a sponge which is too wet.
Never use a knife or a screwdriver.
A scraper with a razor blade will not damage the surface, as
long as it is kept at an angle of 30°.
Never leave a scraper with a razor blade within the reach of
children.
Never use abrasive products or scouring powders.
